### A Process is operating at 6 Sigma:

• A.

We can expect 3.2 defects per million opportunities

• B.

It has a yield of 99.997%

• C.

We can expect 3.4 defects per million opportunities

• D.

It has a yield of 99.9967%

C. We can expect 3.4 defects per million opportunities
Explanation
A process operating at 6 Sigma is considered to be highly efficient and has a very low defect rate. The standard defect rate for a 6 Sigma process is 3.4 defects per million opportunities, which means that out of every million opportunities, only 3.4 defects are expected. Therefore, the given answer of "We can expect 3.4 defects per million opportunities" is correct in relation to a process operating at 6 Sigma.

### A normal Distribution can best be described as:

• A.

Bell-shaped, a variance of 1, the mean/median/mode

• B.

Bell-shaped, symmetrical about the mean, a single mode

• C.

Un-Symmetrical about the mean, a natural tolerance of three standard deviations, unimodal

• D.

Symmetrical about the mean, bell-shaped, discrete data

B. Bell-shaped, symmetrical about the mean, a single mode
Explanation
A normal distribution is characterized by being bell-shaped, meaning that the majority of the data falls around the mean and tapers off towards the tails. It is also symmetrical about the mean, meaning that the data is equally distributed on both sides of the mean. Additionally, a normal distribution has a single mode, indicating that there is one value that occurs most frequently in the data. Therefore, the given answer accurately describes the characteristics of a normal distribution.

### A process is in-control and stable.  Describe the type of variation that exists in the process.

• A.

Special Cause variation

• B.

Natural Variation

• C.

Out-the-ordinary varation

• D.

Non-random variation

A. Special Cause variation
Explanation
The given correct answer for this question is "Special Cause variation". This type of variation refers to the presence of specific, identifiable factors that cause the process to deviate from its normal behavior. These factors can be attributed to specific events, circumstances, or actions that are outside of the usual operating conditions of the process. Special Cause variation is characterized by sporadic, non-random patterns that can be traced back to a specific cause, and it can be addressed by identifying and eliminating the root cause of the deviation.

### Indicate which are examples of variable data: 1)Length, 2)Weight, 3)QA Result, 4)Dollars, 5)Days

• A.

1,3,4,5

• B.

1,2,4

• C.

1,2,4,5

• D.

1,4,5

C. 1,2,4,5
Explanation
Variable data refers to data that can change or vary. In this case, length, weight, dollars, and days are examples of variable data. These values can differ from one situation to another, unlike fixed or constant data. QA result is not considered variable data as it typically represents a fixed outcome or result. Therefore, the examples of variable data in this question are 1, 2, 4, and 5.

### Your control chart shows seven consecutive points on one side of the mean.  What does this indicate?

• A.

The process is in-control (within the UCL and LCL)

• B.

The process appears to be too table and should be questioned

• C.

The process needs to be checked for special causes

• D.

The wrong control chart has been selected

B. The process appears to be too table and should be questioned
Explanation
This answer is incorrect. The correct answer is "The process needs to be checked for special causes." A control chart is used to monitor a process over time and detect any unusual variations or special causes. When seven consecutive points fall on one side of the mean, it suggests that there may be a systematic issue causing the process to deviate from its normal behavior. Therefore, the process should be investigated further to identify and address any special causes that may be present.

Rate this question:

• 7.

### Which Steps should you take when you notice special causes in a control chart?

• A.

Do nothing

• B.

Continue taking data measurements to confirm your belief

• C.

Stop and identify the Special Causes

• D.

Stop, identify the special Causes and eliminate them

D. Stop, identify the special Causes and eliminate them
Explanation
When special causes are noticed in a control chart, it is important to stop and identify them. This is because special causes indicate that there are factors in the process that are causing variation beyond the normal random variation. By identifying these special causes, it becomes possible to understand and eliminate them, thereby improving the overall process and reducing variation. Simply continuing to take data measurements may confirm the presence of special causes, but it does not address the root cause of the problem. Doing nothing is also not recommended as it allows the special causes to persist and potentially worsen the process performance.

### Select the corect mean, median and mode for the following sample:     4,5,6,1,1,2,5,7,5

• A.

4,4,5

• B.

3,5,4

• C.

4,3,5

• D.

4,5,5

D. 4,5,5
Explanation
The given sample is 4,5,6,1,1,2,5,7,5. To find the mean, we add up all the numbers in the sample and divide by the total count. (4+5+6+1+1+2+5+7+5)/9 = 36/9 = 4. The median is the middle value in a sorted list. When we arrange the numbers in ascending order, we get 1,1,2,4,5,5,5,6,7. The middle value is 5, so the median is 5. The mode is the number that appears most frequently in the sample. In this case, 5 appears three times, which is more than any other number, so the mode is 5.

• B.

Construct a SIPOC, Prepare Control Charts, Calculate Cp and Cpk

• C.

Calculate the 3 measures of Central Tendency, Calculate Capability Indices, Prepare Control Charts

• D.

Prepare CTQs, Construct Control Charts, Calculate Capability Indices

A. Construct a histogram, Prepare Control Charts, Calculate Capability Indices
Explanation
The correct answer is to construct a histogram, prepare control charts, and calculate capability indices. Constructing a histogram is the first step in determining if a process is normally distributed. It helps visualize the distribution of data and identify any deviations from normality. The next step is to prepare control charts, which are used to monitor the stability and control of a process. Control charts provide a graphical representation of process data over time and help identify any out-of-control points. Finally, calculating capability indices such as Cp and Cpk helps determine if a process is capable of consistently meeting customer requirements by comparing the process variability with the specification limits.

### A company generates 12,000 orders per month.  Each order has the possibility of 4 errors.  Approximately how many opportunities for defects are provided during the year?

• A.

1,000,000

• B.

84,000

• C.

144,000

• D.

576,000

D. 576,000
Explanation
The company generates 12,000 orders per month, and each order has the possibility of 4 errors. To calculate the total number of opportunities for defects provided during the year, we need to multiply the number of orders per month by the number of errors per order and then multiply that by 12 (the number of months in a year). Thus, 12,000 orders per month * 4 errors per order * 12 months = 576,000 opportunities for defects during the year.

### What can you say about Control Limits and Specification Limits?

• A.

There is no difference between the terms; both are used to indicate if a process is in control

• B.

Control Limits are set by the customers; Specification Limits are derived by the process

• C.

Control Limits are derived by the process; Specification Limits are set by the customer

• D.

Control Limits are typically 3 standard deviations from the mean; Specification Limits are typically 3 standard deviations from the target

C. Control Limits are derived by the process; Specification Limits are set by the customer
Explanation
Control limits and specification limits are two different concepts in statistical process control. Control limits are derived by the process itself and are used to determine if a process is in control or not. They are typically set at a certain number of standard deviations from the mean, often 3 standard deviations. On the other hand, specification limits are set by the customer or the requirements of the product or service. They define the acceptable range of values for a particular characteristic or parameter. Control limits focus on the variation within the process, while specification limits focus on meeting the customer's requirements.

### A process you are monitoring over time exhibits inherent variation.  What strategy should you use to manage the process?

• A.

Take immediate action to identify root causes of the common cause variation

• B.

Increase the specification limits to ensure the process is capable

• C.

Continually and gradually improve the stable process

• D.

Stop the process, identify the causes, and eliminate them

C. Continually and gradually improve the stable process
Explanation
Continually and gradually improving the stable process is the recommended strategy for managing a process that exhibits inherent variation. This approach acknowledges that variation is inherent to the process and focuses on making gradual improvements over time. By consistently analyzing data, identifying areas for improvement, and implementing small changes, the process can be optimized and made more efficient. This strategy recognizes that complete elimination of variation may not be possible, but aims to minimize it and enhance overall performance.

### If no correlation exists between two variables, then:

• A.

As one variable changes, one cannot predict a value for the other variable

• B.

As one variable increases, the other variable decreases

• C.

As one variable decreases, the other variable decreases

• D.

As one variable decreases, the other variable increases

A. As one variable changes, one cannot predict a value for the other variable
Explanation
If no correlation exists between two variables, it means that there is no relationship or connection between them. Therefore, as one variable changes, it is impossible to predict or determine a specific value for the other variable. In other words, the two variables are independent of each other, and the change in one variable does not provide any information or indication about the change in the other variable.

### A control limit...

• A.

Indicates the boundary of the bell curve in a normal distribution

• B.

Indicates that a process event or measurement is likely to fall within that limit

• C.

Indicates that a process event or measurement is likely to fall outside that limit

• D.

Indicates the customer's desired upper or lower performance limits

B. Indicates that a process event or measurement is likely to fall within that limit
Explanation
A control limit indicates that a process event or measurement is likely to fall within that limit. Control limits are used in statistical process control to define the boundaries of a process's normal variation. They are typically set at a certain number of standard deviations from the process mean and help determine if a process is in control or out of control. When a data point falls within the control limits, it suggests that the process is operating as expected and the variation is within acceptable limits.

### The objective of Design of Experiments (DOE) is to

• A.

Map all process steps and determine their average duration

• B.

Establish optimal process performance by finding the right settings for key process input variables

• C.

Establish the best graphing method to illustrate process performance

• D.

Determine the mean and standard deviation of a population

A. Map all process steps and determine their average duration
Explanation
The objective of Design of Experiments (DOE) is to establish optimal process performance by finding the right settings for key process input variables. DOE helps in systematically varying the input variables and analyzing their effects on the output or response variable. By mapping all process steps and determining their average duration, it does not necessarily lead to establishing optimal process performance. Similarly, determining the mean and standard deviation of a population is a statistical analysis technique and not the primary objective of DOE. Additionally, finding the best graphing method to illustrate process performance is a visual representation technique and not the main objective of DOE.

### A six sigma capable process will have..

• A.

Cp = 1.5, Cpk = 2.0 and DPMO = 3.4

• B.

Cp = 2.0, Cpk = 1.5 and DPMO = 6

• C.

Cp = 1.5 Cpk = 2.0 and DPMO = 6

• D.

Cp = 2.0, Cpk = 1.5 and DPMO = 3.4

D. Cp = 2.0, Cpk = 1.5 and DPMO = 3.4
Explanation
A six sigma capable process will have a Cp value of at least 2.0, indicating that the process is capable of producing products within the specification limits. The Cpk value of 1.5 shows that the process is centered within the specification limits and has a small deviation from the target value. The DPMO value of 3.4 indicates that the process is producing only 3.4 defects per million opportunities, which is well within the six sigma quality level. Therefore, the given answer of Cp = 2.0, Cpk = 1.5, and DPMO = 3.4 satisfies the requirements for a six sigma capable process.
